I have not seen a comprehensive list of ways to increase fuel effiency for a Titan. I hope this becomes one.

My question:
Besides better driving habits, what are the ways to increase MPG? If you have computer data to back up your statements, all the better. I'm looking at lifting a Titan about 4 to 6 inches and would like to get the most fuel that I can considering lifting is going to butcher the already low MPG rate. Thank you for your help and advice.

CNN just had a report on how they lowered the 08 model vehicles (any vehicle) estimated MPG on the sticker by 12% to more accurately reflect real driving conditions.

isn't a single mpg (or so) increase a pretty substantiated increase when making the switch from dino to synth oil?

i seem to recall seeing that one come up quite a bit in past threads.

Possible, but it's not good to go into an oil change expecting hp or fuel changes usually. I just had to face it.......she's a thirsty lil devil!

I've heard it all over said that putting an air filter, or installing a better exhaust will increase MPG's because they also increase power so at lower speeds and RPM's the engine doesn't work as hard and thus you save fuel. Any truth to this? And if that's true, any suggestions to parts?

Suggestion.......go buy a Fram or Airraid drop in filter. Maybe reset the ecu, and log your mileage vs. before. That way you can inexpensively try an aftermarket part and see. It will be minimal to low usually. Then if you do see some increase you might go and spring for the exhaust then?!?!

I have always thought of it as... the more efficient the motor the more power and mpg you get. So the more power to weight ratio, the better the mpg. So if you can do the power adders, you can save mpg. The problem with this, and why it usually doesnt work, is you tend to step on the gas more so you can feel the power. Thus decreasing mpg.

For the first 50,000 miles my Titan averaged 13.9 MPG. I have a split exhaust and Volant air intake. I had the 2 degree advance done and switched from 87 to 89 octane fuel and since then I've been averaging about 15.8 MPG. I haven't changed my driving style or anything else, just the 2 degree advance and octane rating. Considering the small difference in cost for the fuel and the significant increase in fuel mileage I think this is a worth while investment.

I'm out of my field of knowledge here so please work with me. I heard that there are settings on your titan's internal computer that can be changed to cause the air/fuel mixture ratio to make the injectors spray less fuel but also tune your truck to make it run leaner thus better performance and SAVE GAS. Any truth to this?? Apparently, from the factory titans (and all cars) are tuned to make the air/fuel mixture better for emissions not neccessarily for gas mileage.

My Titan has a Magnaflow exhaust and AEM intake and consistantly get 15.5 mpg and thats with hitting it hard a couple time each tank....I tried to burn a whole tank with a light foot and I COULDNT DO IT.....I NEED HELP.....

any suggestions...I think charter hospital went out of bussiness.LOL

Why would a person go out to buy a Titan when it says right on the sticke ( I GET CRAPPY GAS MILEAGE ) and knowing that buy one just to later complain about mileage issues. If you wanted good mileage shoulda bought a car.

The most efficient way to improve fuel mileage is also
the least popular way...........keep the RPM below 2000
when cruising & below 3000 when accelerating.
I know I can't do it for long.

Hey Stan,
Using the information you provided I calculate the following:
With your current setup, and $3.05 a gallon for 89 octane you are spending 19.3 cents every mile you drive. Your old setup at $2.95 a gallon for 87 octane cost you 21.2 cents every mile. Sounds like a savings...right? So you are saving 1.9 cents a mile with your current setup. OK - let's estimate you spent roughly $1000 on your timing advance, exhaust & air intake. Do you know how many miles you will have to drive before you make up the cost of the mods and with the more expensive 89 octane? The correct answer would be 52,631.58 miles. Now do you think it is a worthwhile investment?

Yes because most people buy mods with cash. So then now you will be technically spending less money a month witch means more money for something else like mods and less in bills.

I have never felt or noticed a difference with 89 octane. I have found a minimal differance with 91 octane, but the additiona cost isn't worth it to me. I bought a gas hog and I knew it prior to purchasing. Then I lifted it on big wheels and tires, so my milage is worse. But I guess cool rides just cost more!

I didn't post that last comment to annoy anyone, I just wanted the reality of "modding to save on fuel" to hit home. Trust me when I tell you that I am feeling the pain at the pump as well. I wish there was an easy fix, but I haven't found one yet.

Figuring at $3.35 and $3.45 for 87 and 89 octane respectively, that calculates a payoff at 33,333 miles. On a side note, I find that if I have more horsepower, I tend not to realize much savings as the foot tends to want to feel more of the power. Just like those ideal fall days with lower air temp and humidity...I just can't resist.
